CHAIN-PUMP BUCKET.

SPECIFICATION formingpart of Letters Patent No. 234,588, dated November16, 1880.

Application filed July 27, 1880.

To all whom it may concern:

Be it known that we, GEORGE W. LARAWAY and FRED G. ROCKWELL, ofHartford, in the county of Hartford and State of Connecticut, haveinvented a certain new and useful Improvement in Connection for SecuringBuckets to their Chains, of which the following is a description,reference being had to the accompanying drawings, where- Figure l is aside view of a bucket embodying our said improvement. Fig. 2 is a viewof the same in central vertical section, on the plane a; a".

Our invention relates to that class of chainpump buckets and theirconnections in which each bucket is made of rubber or other elasticmaterial, and perforated vertically for the pas sage of itsconnecting-link, such construction being shown in Patents of the UnitedStates Nos. 167,286, 206,854, and 218,746; and our invention consistssolely in the means for connecting such buckets to the links of theirlifting-chains-to wit, a series of pins passing through centraltransverse openings in the straight portions of the links, incombination with washers interposed between the buckets and said pins,by which construction each bucket. may be compressed or expanded toincrease or reduce its diameter, and be held in its adjusted position toconform to the diameter of the pump-barrel, the bucket being alsocapable of ready removal when its upper side becomes worn and itrequires to be inverted, or to substitute a new one therefor when pastrepair, by simply withdrawing the confiningpins and pressing out thehooked end of the loop of the link, all of the buckets being reversedwithout removal by changing the direction of the chain, this latterfeature being common to all buckets of this class.

The letter (t denotes the link, a metal bar bearing a loop at each endfor attachment to the links next insuccession.

The bucket is a hollow rubber globe, b, pierced with a central hole,whereby to be hung upon the link, and peripherally provided with aflange, 0, having converging sides, so as to come to an edge, or nearlyto an edge,

(No model.)

we preferring that the edge, so to call it, should have a face aboutone-sixteenth of an inch wide. The rubber globe-bucket rests underneathon a cross-pin, d, traversing the diameter of the link, with a washer,e, interposed. A similar cross-pin, d, confines the bucket on the topwith a similar interposed washer, c

The link-bar is pierced with a number of radial or diametric holes, f,for either or both the cross-pins d (1, so that when it becomesdesirable to enlarge the diameter of the whole bucket, particularly theperipheral flange, the globe of rubber may be pressed togethervertically for that purpose, and held so pressed by placing one or boththe cross-pins in appropriate ones of the holesf.

We have called the bucket a globe in form. A form approaching theglobular will answer but we prefer a globe.

lVe have spoken ofa single peripheralflange. More than one may be used.

The eripheral flange is provided with a drip-hole, g, and the body ofthe globe is also provided with a nearly central drip hole or holes, hh.

We have said the material of the bucket is rubber. Any othersuitableexpansible material will answer.

The novelty in this rubber bucket consists mainly in the shape and formthereof, the body being spherical and the annular flange being V-shaped,(in section,) so that the upper and lower halves of the bucket are thesame in shape and form, to the end that when the bucket has ridden onthe chain in one position till its efficiency is destroyed or greatlyimpaired the bucket may be placed on the chain the other half uppermost,compressed to fill the tube, and operated in that position, thuspractically almost, if not quite, doubling the life and usefulness ofthe bucket, as compared with those buckets designed to' have only oneposition on the chain.

As before stated, we are aware that chainpumps having rubber bucketshave been employed; and in the present application we lay no claim toanything pertaining to the construction of such buckets, but only to ourimproved means of securing and adjusting the elastic buckets b of achain-pump, substantially as set forth.

same to their lifting-chains. GEORGE \V. LARAWAY.

We claim as our improvement- The links a, with their perforations f,pins (1 d, and washers 0 e, in combination with and for adjusting andsecuring in place the FRED O. ROCKWELL. Witnesses:
